BD is a global medical technology company that pride's itself on advancing the world of health by improving medical discovery, diagnostics and the delivery of care. With thousands of patented medical devices and unique procedures under their belt, it comes as no surprise that they need innovative training solutions to match. Our team at Accomplice was asked to create an augmented reality training system for BD's WavelinQ™ EndoAVF procedure. 

THE CHALLENGE

Augmenting medical training

The WavelinQ™ EndoAVF System is a device and procedure combo that revolutionizes the way arterial-venous fistulas are created in patients who qualify for candidacy. In its 10 year history, physicians training has traditionally been performed on cadavers in a clinical setting. There are many issues that exist with the current training that our solution aimed to solve.

ACCURATE CANDIDATES

Cadaver limbs are not screened for candidacy prior to being purchased and shipped for training. This means you may or may not have true candidates for physicians to train on.

PORTABILITY

Other training units exist, but are not portable since weighing over 50 pounds each. They are also very expensive, costing ~$90k per unit. 

UN-RESTRICTED AVAILABILITY

Physicians training is currently held bi-weekly with a max of 12 attendees at each session. This directly limits the scale and reach of the value the procedure can bring.

COST EFFICIENCY

Each attending physician needs to be flown out to the training facility and housed for the two day training. The clinical facility also needs to be rented, cadaver limbs purchased, lunches catered, and so on.

OUR GOALS

Emerging tech meets medicine

We set off to create a system that would solve the four main points from above, with the main goal being to ultimately replace cadaver-based training. The system consists of an iPad that will drive the experience from a custom application, an iPod for 6DoF tracking, Polhemus micro-sensors for catheter tracking, a forearm prosthetic, and an arm mount that mimics a C-Arm’s movement. As the sole designer on the team, I spearheaded the following streams:

01. Research & Discovery

02. Information Architecture

03. UX Design

04. UI / Visual Design

RESEARCH & DISCOVERY

Scrubbing up and diving in 

In order to properly design the system and account for all the possible states that needed to be considered, I had to understand the ins-and-outs of the procedure. This meant "scrubbing up" and attending physicians training. I was fortunate enough to be able to observe the procedure on cadavers, document the equipment used, and interview clinical specialists.

INFORMATION ARCHITECTURE

Mapping out the procedure

Following physicians training, I was able to map out the organization and user flow. The solution would consist of a patient library where physicians could choose from multiple cases, be able to determine candidacy based on vessel measurements, and if a candidate, jump into the AR experience of the simulated procedure.

ARTS SITE/USER FLOW MAP

This map outlines how a user will flow through the main segments of the app. It accounts for user actions, unique screens or modals, and the choices they need to make to get into the AR experience.

PROCEDURE SCREEN USER FLOW

This accounts for all the logic the AR experience would need to account for within the context of the available actions.

UX DESIGN

Emerging tech meets medicine

Following physicians training, I was able to map out the organization and user flow. The solution would consist of a patient library where physicians could choose from multiple cases, be able to determine candidacy based on vessel measurements, and if a candidate, jump into the AR experience of the simulated procedure.

DETERMINING CANDIDACY

Physicians may know the anatomy, but learning how to correlate vessel measurements to determine a patient's candidacy is a major goal of the product's success. 

REPLICATING FAMILIARITY

Ensuring key screens resemble the devices that the procedure is performed on helped bridge the gap between a user group that may not be tech-savy.

USER TESTING FOR ADDED VALUE

We tested the wireframes on a few of the clinical specialists from BD to gain a greater insight on what and how to present the information needed to successfully train physicians.

UI / VISUAL DESIGN

Working with the exsisting 

BD had a pretty establish brand system, however this was mainly from a marketing or paper collateral standpoint. I was able to inform most of my design decisions from their marketing website, as well as introduce some new UX patterns. Throughout this project, every screen had to go through multiple levels of approval in order to get produced. BD Marketing had to ensure the brand was used correctly, BD Design focused on how this experience measured against their other digital products (mainly online apps), and BD Legal combed through every word to ensure FDA compliance.

GUIDED PATIENT SELECTION

Walking physicians through the five primary considerations, while isolating relevant information helped solidify learning.

PROCEDURE PLANNING & MORE

Though physicians found it helpful to see all their choices laid out, a sequenced unveiling helped. Also, adding an overview to educate users on the benefits and challenges of their selection.

FLUOROSCOPIC CONTROLS

Leveraging the layout that physicians were familiar with, I organized controls in a manner that were easy to understand and flow through the procedure.

OUTCOMES

Survey says...

Following its debut of being incorporated into physicians training (as a rotation, not a substitute) I personally surveyed each attendee to gather their thoughts on ARTS and quantified it. With resoundingly positive feedback, ARTS has expanded uses and in addition will become a training tool for all clinical specialists. It has also been showcased at multiple conferences on endoscopic medicine and will continue to be iterated upon and improved.
